Actually, it may have been you that pointed me to it – so thanks for that! I use it with my students, too, with one slight difference: to make them understand how the world “outside” simply IS - and that they have to be very skilled rhetoric warriors in addition to designers to convince these too-powerful yet aesthetically underdeveloped decision-making marketing departments. Designers need to be able to say “No, I’m not doing that. That is poor design. Period.” If they lose the client, they drive a taxi until they find one who listens.
